(5) CdtPolyRedPairProof (UPPER BOUND (ADD(O(n^1))) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

F(s(0)) → c1(F(p(s(0))))
We considered the (Usable) Rules:

p(s(0)) → 0
And the Tuples:

F(s(0)) → c1(F(p(s(0))))
The order we found is given by the following interpretation:
Polynomial interpretation :

POL(0) = [3]   
POL(F(x1)) = [4]x1   
POL(c1(x1)) = x1   
POL(p(x1)) = [3]   
POL(s(x1)) = [5] + x1
